Heil Quaker ICP 1160193 Limit Switch

The Heil Quaker ICP 1160193 Limit Switch is a critical safety component designed for precise thermal regulation in residential and commercial furnaces, air handlers, and heat pumps. This adjustable limit switch features a versatile temperature range of 140-180°F with a fixed 20°F differential, allowing technicians to fine-tune the high-limit cutout based on specific equipment requirements. As a genuine ICP OEM replacement part, it ensures proper fitment and restores the system's ability to prevent overheating by interrupting the burner or heating element circuit when air temperatures exceed safe thresholds.

Constructed for durability in high-cycle environments, the 1160193 manual reset limit switch (also categorized as a switch limit disc B) is compatible with a wide array of brands under the International Comfort Products umbrella, including Heil, Tempstar, Comfortmaker, and Arcoaire. Integrating this HVAC high limit sensor is essential for resolving common service issues such as frequent system cycling, blower motors running continuously, or complete heating failure. Always verify the opening temperature and differential against the original equipment tag to ensure the safety circuit remains within the manufacturer's design specifications.

• Adjustable Thermal Control: Provides flexibility with a 140°F to 180°F adjustment range to meet specific plenum temperature requirements.
• Broad ICP Compatibility: Direct replacement for various Heil Quaker, Kenmore, and Tempstar models, reducing the need for universal truck stock.
• System Protection: Acts as a primary safety fail-safe to prevent heat exchanger damage and hazardous operating conditions.
• OEM Precision: Genuine ICP 1160193 engineering ensures the 20°F differential maintains accurate reset points for consistent performance.

What are the symptoms of a failing ICP 1160193 limit switch?
A faulty switch typically causes the furnace to short cycle, or in some cases, the indoor blower motor will run indefinitely as a safety precaution to cool the heat exchanger.

Can this switch replace a fixed temperature limit?
Yes, provided the required cutout temperature falls within the 140-180°F adjustable range and the physical disc mounting is compatible with the existing bracket.

Is the 20°F differential adjustable?
No, while the main temperature setpoint is adjustable, the 20°F differential is fixed, meaning the switch will reset once the temperature drops 20 degrees below the cutout point.
